SW2-SW3 Green/Red LED Control: The default mode for the Green/Red LED Control
is the internal control. The LED is normally red. When a card is read, the LED flashes
green. When the setting is “Off”, the Green/Red LED is controlled externally. The
external control lines can then be used to operate the LEDs.
SW4 Master/Slave: The switch is used to select the Reader’s communication interface.
When the setting is “On”, the Reader is controlled by Wiegand signal. When the setting
is “Off”, the Reader is for RS-485 signal.
SW5-SW7 ID Setting: Switch 5 to switch 7 is used to set the Reader’s ID for wiring in a
daisy chain.

SW6 OFF OFF ON ON OFF OFF ON ON
SW7 OFF ON OFF ON OFF ON OFF ON
SW8 RS-485 Terminal Resistor: When the setting is “On,” a 120-ohm resistor is
connected between RS-485+ and RS-485-. This setting is used in the last device when
multiple RS-485 devices are connected together.
Note: After changing the dip switch settings, the unit must be reset by powering down then
up again before the new switch setting will take effect.

1.2.3 Defining the ID Number of GV-SR1251 by Using GV-Reader
Config Utility
Through a single RS-485 cable, you can connect up to 8 GV-Reader1251 / 1352 V2 /
SR1251 to a GV-AS Controller. To form a daisy chain connection, follow the steps below to
define each reader’s ID number by using GV-Config Utility.
1. Install and download GV-Reader Config Utility. For details, see 2.4 Installing GV-
R/RK/DFR Config AP.
2. Run GV-R/RK/DFR Config AP.
3. Select the COM port that is connected to the reader and click Open COM. The red
square next to the COM port box should change to blue to indicate the COM port is
correct.
4. Select an ID number for the reader. The ID number ranges from 0 to 7.
5. Click Setup. The serial number and firmware version of the reader will be automatically
detected. The settings are sent to the reader.
Note:
1. To define the ID number of GV-Reader1251 / 1352 V2, use the switches at the back of
the reader.
2. GV-SR1251 only reads UID. Therefore, the Only Read GID option in the GV-
R/RK/DFR Series dialog box is not functional for GV-SR1251.

1.3 Connecting the Reader to GV-AS Controller
The GV-Reader1251 / 1352 V2 / SR1251 is compatible with any standard access controllers.
The following diagrams illustrate how to connect the GV-Reader1251 / 1352 V2 / SR1251 to
GV-AS Controller through Wiegand interface or RS-485 interface, and how to connect the
GV-Reader1251 / 1352 V2 / SR1251 to third-party access controllers and GV-DVR/NVR.
For GV-Reader1251 / 1352 V2, after you wire the connection between the reader and the
access controller, ensure the related switch setting on the GV-Reader1251 / 1352 V2 is
configured correctly.
Note: Each reader consumes 60 mA of power. The total power consumption of the output
devices and readers connected to GV-AS Controller must be under 2.5A (for GV-CS1320),
3A (for GV-AS1620, GV-AS210 / 2110 / 2120), 3.5A (for GV-AS410 / 4110) or 5A (for GV-
AS810 / 8110). Connect an external power supply if the power supplied from GV-AS
Controller is insufficient.

2. Type the username and password to login.
3. In the left menu, click Extended Reader. This page appears.
4. If the readers are connected using RS-485, select the RS485 checkbox in front of the ID
number. The ID number must match the ID you configured using SW5 – SW7 (for GV-
Reader1251 / 1352 V2) or GV-R/RK/DFR Config AP (for GV-SR1251).
5. Leave the serial number field blank.
6. Select a door/gate for the reader under Function. Click Submit.

1.3.3 Connecting to GV-DVR/NVR and Third-Party Access
Controllers
GV-Reader1251 / 1352 V2 / SR1251 is also compatible with third-party access controllers.
With its compatibility, you can also add a GV-DVR/NVR to this connection to empower your
management.
After connecting the GV-Reader1251 / 1352 V2 / SR1251 to the access controller through
the Wiegand interface, connect the reader to GV-DVR/NVR via GV-COM, GV-Hub or GV-
NET/IO Card V3.1.
